I create the jekyll-web_monetization gem which aims to make it easy to add payment pointers to Jekyll sites. You can set a site-wide payment pointer, which is great if it is your own site. Or, if you have multiple authors, you can set per-post payment pointers in the the page's YAML front matter.
To use this plugin and receive payments from Web Monetization you will need a payment pointer. A payment pointer is an address at which you can receive streaming payments from the Web Monetization API. You can set up a payment pointer by creating a digital wallet with one of the providers listed on the Web Monetization API site.
Great idea, I'm sure people will use it.
